x =input("Enter Your age-") // 23

print(x)

output

int() Type cast

x = int(input("Enter Your age-")) // only enter integer value

print(x)

output

23

float() type cast

x = float(input("Enter Your age-")) // 44

print(x)

output

eval() type casting - any types of value converts 

x = eval(input("Enter Your age-")) // enter- 0b1111( 15 binary number)

print(x)

output
